1) Substances possessing a dibenzo-p-dioxin (diphenylene dioxide) structure show blue to bluish green coloration in sulfuric-nitric acid or conc. sulfuric acid solution when added with potassium nitrate, sodium nitrate, potassium chlorate, or other oxidation agents. This reaction was discovered by Tomita more than 20 years ago and it was applied to the detection of dibenzo-p-dioxin derivatives by paper chromatography in the present series of work.
2) Coloring reagent was an ethanolic solution of potassium nitrate followed by spraying of conc. sulfuric acid.
3) Paper chromatography was carried out on several dibenzo-p-dioxin derivatives with ordinary and silicone-treated filter paper (Toyo Roshi No. 50), using various solvent systems. Results obtained are listed in Table I.
4) This coloration method can be applied to the paper chromatograpay of alkaloids possessing a dibenzo-p-dioxin structure such as trilobine, isotrilobine, and menisarine.
